<h2 id="题目"><a href="#题目" class="headerlink" title="题目"></a>题目</h2><p>请你设计一个数据结构，支持 添加新单词 和 查找字符串是否与任何先前添加的字符串匹配 。</p>
<p>实现词典类 WordDictionary ：</p>
<ul>
<li>WordDictionary() 初始化词典对象</li>
<li>void addWord(word) 将 word 添加到数据结构中，之后可以对它进行匹配</li>
<li>bool search(word) 如果数据结构中存在字符串与 word 匹配，则返回 true ；否则，返回  false 。word 中可能包含一些 ‘.’ ，每个 . 都可以表示任何一个字母。</li>
</ul>
<h2 id="示例"><a href="#示例" class="headerlink" title="示例"></a>示例</h2><p>示例一：</p>
<blockquote>
<p><strong>输入</strong>：<br>[“WordDictionary”,”addWord”,”addWord”,”addWord”,”search”,”search”,”search”,”search”]<br>[[],[“bad”],[“dad”],[“mad”],[“pad”],[“bad”],[“.ad”],[“b..”]]<br><strong>输出</strong>：<br>[null,null,null,null,false,true,true,true]</p>
<p><strong>解释</strong>：<br>WordDictionary wordDictionary = new WordDictionary();<br>wordDictionary.addWord(“bad”);<br>wordDictionary.addWord(“dad”);<br>wordDictionary.addWord(“mad”);<br>wordDictionary.search(“pad”); // return False<br>wordDictionary.search(“bad”); // return True<br>wordDictionary.search(“.ad”); // return True<br>wordDictionary.search(“b..”); // return True</p>
</blockquote>
<h2 id="提示"><a href="#提示" class="headerlink" title="提示"></a>提示</h2><ul>
<li>1 &lt;= word.length &lt;= 500</li>
<li>addWord 中的 word 由小写英文字母组成</li>
<li>search 中的 word 由 ‘.’ 或小写英文字母组成</li>
<li>最多调用 50000 次 addWord 和 search</li>
</ul>
<h2 id="解题"><a href="#解题" class="headerlink" title="解题"></a>解题</h2><p>本题要进行插入和搜索，可以使用前缀树来实现，前缀树类实现如下：</p>
